7/10 C-
This episode was tepid at best. Nothing hugely exciting or controversial, and the only real significant information was about NASCAR. The way the video was segmented into three parts also damaged the flow from segment to segment. The cinematography was epic and some of the jokes were good, but that didn't really didn't give this episode the more memorable kind of content that TopGear is known for. It was nice to see James' response to the 458, but the Mercedes SLS was really the only car we hadn't seen on the show before (yes, I'm aware the GT3 RS has been updated). I came close to giving this episode a 6, but the racing and excellent imagery bumped it up to a 7 for me.
Edit: I also must add that my opinion about this episode was swayed by Clarkson's mishandling of a firearm. I know that handguns are outlawed in the UK, but that still does not mean that Top Gear should be completely incompetent when it comes to firearms safety. This is a large part of why I almost scored this episode a 6 out of 10. James has done this on at least two occasions that I can remember right now, and Jeremy doing the same shows a complete disregard for the danger involved when handling firearms.
All guns are loaded. Never point a gun at something you don't want to kill.
